Overview
Zoetis is a global animal health company with most revenue from companion animal products and a significant livestock portfolio. Its moats are anchored in regulated product approvals and cGMP manufacturing, a scaled global commercial and veterinary specialist network, strong brands, and a large IP portfolio. Competitive pressure comes from industry consolidation, generic alternatives after loss of exclusivity, and shifts in purchasing power toward large clinic groups and retailers/e-commerce.
